The permitted voltage range is:● 207 to 300 V AC for:– Connection between phase and neutral conductor– 2-pin connection between phase and neutral conductor● 360 to 520 V AC for:– Connection between phase and phase– 2-pin connection between phase and phase– Economy circuitLine supply voltage monitoring POM4320The measured values of the POM are used for monitoring.The permitted line voltage range is 360 V AC to 520 V AC.9.7.4 Monitoring of the 24 V DC supply voltageThe 24 V DC supply voltage is monitored on the CIM. If the 24 V fails, the power outputs ofthe POMs are automatically deactivated. There is no manufacturer-specific diagnosticsalarm in the case of failure of the 24 V supply. Instead, the PROFINET/PROFIBUS controllerdetects and signals failure of the HCS system or individual modules.
